Aria Vents Flushmount Lite Matte Black 3"x10" - PRO, $52.99 USD/Box, LL Flooring (Lumber Liquidators)

Customize this vent by trimming your flooring material to fit the center tray. With a sleek flush mount installation, the surface remains uninterrupted. Its airflow is comparable to standard vent grills. The design is ultra-minimal, frameless, and sits flush with no rim, displaying only a single rectangular air channel. This model requires mounting before surface material is laid. Professional installation is recommended.
